Purpose

Color is a basal quality in human perception. Color can be used for communication, it is a very efficient way to direct attention, and significance can assigned to an object with color. However, color is a historical and cultural phenomenon, and is subject of continuous aesthetical changes. Furthermore, it should be taken into consideration that a rather high percentage of population has a perception disorder ranging from difficulties to discriminate between red and green to complete color blindness.

Guidelines

Choose colors by selecting the appropriate theme color or system color. You can use the CheckColorRoles theme to detect bugs regarding the use of system colors in your application.

Never use color as a primary method of communication, but as a secondary method to reinforce meaning visually.
